Pro-Graad PG-356 Aluminum Wheel Reducing Flanges are the ideal solution for achieving a perfect fit and high precision when mounting non-woven convolute deburring wheels. Precision machining of the Pro-Graad aluminum wheel flanges guarantees a snug fit and exceptional durability, promising long-lasting performance. What sets these flanges apart is their one-piece design, which eliminates the risk of any weak points or potential failures, making them robust and reliable for various applications. They incorporate integrated contact outer rings to further enhance their fit, adding to their overall sturdiness. Versatility is a key feature of these flanges, as they are compatible with non-woven convolute deburring wheels. This makes them suitable for use on stationary machines like double grinding machines (bench grinders), buffing machines and allows them to be used with deburring wheels ranging from 1/2" to 4" in width. Additionally, the flanges include integrated vent holes that promote efficient heat dissipation. This is crucial during extended usage, as it helps prevent the buildup of excess heat, ensuring the longevity of both the flanges and the deburring wheels. Pro-Graad PG-356 Reducing Flanges are a reliable and versatile solution for precision and durability in mounting large center hole wheels for use in deburring and finishing applications.
